Which of the following is a passive wireless packet analyzer that works on Linux-based systems?

OpenVAS is an open-source network vulnerability scanner used to identify security weaknesses in hosts; it has no wireless packet capture or 802.11 monitoring functionality.

Burp Suite is a web application security testing proxy focused on HTTP/HTTPS traffic interception and manipulation; it cannot capture wireless 802.11 frames.

tshark is the command-line packet capture tool from the Wireshark suite and can capture traffic on wireless interfaces, but it is a general-purpose analyzer and not specifically a passive wireless detector designed around 802.11 reconnaissance.

Kismet places wireless interfaces into monitor mode, allowing it to passively capture all 802.11 frames in range without injecting or transmitting any packets. It is purpose-built for Linux-based systems and supports passive detection of networks, clients, and encrypted traffic without alerting the target network.
